Possible Causes/Solution
Alternator, AVR or wiring is damaged.
Contact servicing dealer.
Generator output is shorted or severely overloaded. Iden-
tify and clear the overload, and then restart.
Voltage supply to the AVR is high. If an external battery
charger is in use, contact installing dealer to correct instal-
lation. If an external battery charger is NOT in use, contact
servicing dealer.
Probable causes are:
1) The generator was temporarily overloaded.
2) The output was temporarily shorted. Try to restart the
unit.
AVR is damaged. Contact servicing dealer.
Probable causes are:
1) Replace AVR filter. Inspect fan.
2) Intake or exhaust air path is blocked. Check intake and
exhaust.
3) The BIG fan is not running (only runs when the engine
is running). KEEP FINGERS AWAY FROM FAN HOUS-
ING- PERSONAL INJURY CAN OCCUR IF FAN IS RUN-
NING. Contact servicing dealer.
4) Air leak in AVR enclosure. Contact servicing dealer.
5) Engine running too hot. Inspect air intake and exhaust.
6) Ambient temperature has risen above 60º F. Derate the
generator output per specifications.
An incorrect voltage and frequency has been detected
during starting. Probable causes are:
1) Alternator damage. Contact servicing dealer.
2) Generator has started into a severe load. Manually
operate transfer switch back to utility position and try to
restart unit. If problem persists, remove load and attempt
to restart unit again.
3) The engine may not be reaching its prescribed speed.
Proceed as follows:
•
Verify stepper motor is moving and linkage is free.
•
Verify stepper motor is plugged in.
•
Verify gas pressure is within specified limits.
The generator output voltage is too low. Probable causes
are:
1) The load is too large. Remove load and attempt to
restart unit.
2) Alternator or AVR damage. Contact servicing dealer.
